Transition

A set of classes for implementing transitions between application screens.

New in version 1.0.0.

Changing transitions

You have multiple transitions available by default, such as:

• MDFadeSlideTransition

  state one: the new screen closes the previous screen by lifting from the bottom of the screen and changing from transparent to non-transparent;

  state two: the current screen goes down to the bottom of the screen, passing from a non-transparent state to a transparent one, thus opening the previous screen;

Note

You cannot control the direction of a slide using the direction attribute.
